Trouble recording 24 to VCR

Did anybody try to record the last episode of 24 to DVD or VCR? I recorded it to TiVo and a friend wanted me to record it on VHS for her to watch since she missed it. It was fine on TiVo but when I recorded it to VHS (2 times on different tapes) the voices were scrambled. It isn't the VCR because I tried it with a different program and it worked fine (recording). Did the producers do something so it can't be pirated or ?? Can someone else try it and see if they have a problem? Thanks!!
